General Information 



Product View 




Overview 

Both the MacBook Pro (17-inch) and MacBook Pro (17-inch Core 2 Duo) represent the a new 
generation of MacBook Pro professional notebooks. The original MacBook Pro (17-inch) is built 
upon the Intel Core Duo chip, while the new MacBook Pro (17-inch Core 2 Duo) is based upon 
the more recent Intel Core 2 Duo chip, increasing processor speeds to 2.33GHz. 

In comparing the MacBook Pro (both the 17-inch and the 17-inch Core 2 Duo) to the previous 
generation of 17-inch aluminum PowerBook G4s, they may have a similar look, but only the 
power cord and power adapter AC plug are the same. 

The exterior of the new MacBook Pro (17-inch Core 2 Duo) differs from the preceding MacBook 
Pro (17-inch) in one small but clever way. The LED for the iSight camera no longer depends on 
opening in the display bezel to be visible. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 6 



Also new is a MagSafe Airline Adapter, available for both the MacBook Pro (all models) and the 
MacBook (all models). The MagSafe Airline Adapter fits into the EmPower port nearest your airline 
seat. Some airlines may have 20 mm in-seat ports that require the use of an additional adapter 
(included in the kit).

New Parts and Procedures 

This section not only compares the new MacBook Pro (17-inch Core 2 Duo) to the previous 
MacBook Pro (17-inch), but as a combined manual for both MacBook Pro 17-inch models, it may 
also reiterate how they differ from previous PowerBook G4 17-inch models. Unless specified, 
comments can be applied to both 17-inch MacBook Pro models. 

Main Logic Board 

The hallmark of the MacBook Pro (17-inch) and MacBook Pro (17-inch Core 2 Duo) is the Intel 
Core Duo and Core 2 Duo chip, respectively, each with a ATI Mobility Radeon x1600 graphics chip. 
The microprocessor is soldered to the main logic board. It is not upgradable. 

All ports in both MacBook Pro 17-inch models remain the same. The port differences between the 
MacBook Pro and the PowerBook G4 include: the MagSafe power port and second USB port on 
the left, as well as ExpressCard/34 replacing what was previously a PCMCIA card slot. The security 
lock slot is on the right side of the system. Due to all the port re-arrangements, the new logic 
boards will not fit in any Macintosh 17-inch PowerBook G4s or vice versa. Composite and S-video 
connections are now only available using an optional Apple DVI to Video adapter. 

The boot architecture of the MacBook Pro is based on Extensible Firmware Interface (EFI), replacing 
Open Firmware (OF) of PowerBook G4 days. Boot snag keys such as "C" for boot from the optical 
drive, "N" for network boot, and "T" for Target Disk Mode stay the same under EFI. To launch Apple 
Hardware Test (AHT) from the Mac OS X Install disc, you must hold down the "D" key during boot. 

Unlike the MacBook Pro (17-inch), the MacBook Pro (17-inch Core 2 Duo) now utilizes JST wire 
bundle connectors that disengage by lifting up and pulling the connector out of its mating 
part on the logic board. To reconnect, just snap the connector back in, making sure it is seated 
securely. The fans, thermal sensors, and backup battery all use this connector. 




. c 



Main Memory 

The memory connector is a stacked memory design. The MacBook Pro (17-inch) supports up to 
2GB of RAM, and the MacBook Pro (17-inch Core 2 Duo) supports up to 3GB. However, note that 
in the latter, while you will have a perfectly bootable system with two (2) 2GB RAM modules— 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 8 



and even About This Mac will report 4GB of installed memory— the system will only be able to 
address 3GB of that installed RAM. 

See MacBook Pro (Core 2 Duo): Memory Specifications for more information. 



Main Battery 

Both MacBook Pro 17-inch models use battery packs built with the same lithium polymer 
battery technology used in our iPod product line, though the basic chemistry is no different 
than previous lithium ion cells. An unchanged battery controller keeps the battery calibration 
procedure the same as it has been since the PowerBook G4 line. 



Power Adapter 

All MacBook Pro models use an Apple 85-Watt Portable Power Adapter with the revolutionary 
MagSafe power connector. It is not compatible with any previous notebook computer. 

The MagSafe connector consists of a magnet inside the computer and an attraction plate in the 
DC plug on the power adapter. Since the power port has a magnet built in, whenever you service 
the system it is recommended to put a piece of tape over the connector to avoid materials such 
as screws and washers from being inadvertently drawn into it. 




- — . ■• 



The DC plug consists of five pins. Each pin is spring loaded. The center pin is a sense pin (2). This 
center pin must make contact with the computer before power is applied. Power is carried on the 
remaining four pins (4). The outer pins are positive terminals, the inner pair are the return paths. 

Since there is no up side to the DC plug, it can go either way. To support this design, the power 
LED (1) is on both sides of the connector. As always, the LED will glow amber when charging the 
battery, and green when supplying power to the system but not charging the battery. 




MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 9 



Top Case 

For both MacBook Pro 17-inch models, the sleep magnet is located on the side of the display bezel, 
and the sleep sensor is located to the right side of the top case just around the bottom of the 
perforated speaker openings. 

Keyboard 

Both 17-inch MacBook Pro keyboards utilize flex cables that are incompatible with previous 
PowerBook G4 keyboards. Also, this flex cable difference renders the 15-inch MacBook Pro 
keyboard incompatible with either 17-inch MacBook Pro model. 

The MacBook Pro (17-inch Core 2 Duo) keyboard backlighting has been improved over the 
MacBook Pro (17-inch) model. In addition, the programming of the caps lock key was changed to 
fix a developer keyboard mapping issue, and thus cannot be used in the previous MacBook Pro 
(17-inch) or the caps lock key will not be recognized. 

Mass Storage (hard drive and optical drive) 

The hard drive interface for all MacBook Pros is Serial ATA (SATA);thus, previous PowerBook hard 
drives will not work in this system. 

The optical drive in both 17-inch MacBook Pro models is basically the same mechanism used 
in the PowerBook G4 (17-inch Double-Layer SD), but it has updated firmware. You should not 
interchange the two parts. 

AirPort Extreme 

The MacBook Pro (17-inch) uses the same AirPort Extreme card as the 15-inch MacBook Pro and 
does not support Bluetooth. It is the same form factor used in the iMac (Early 2006). However, 
there are two version of these cards. We have structured service parts to keep them separate. 

The MacBook Pro (17-inch Core 2 Duo) utilizes a newer AirPort Extreme card with a three-wire 
antenna solution. The length of each wire and its color will help distinguish which wires go to 
which terminals on the card (black = longest/left, gray = medium/middle, blue = shortest/right). 




The AirPort antenna for both 17-inch MacBook Pro models is located in the clutch barrel 
underneath the gray plastic window. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 10 



Bluetooth 

Each 17-inch MacBook Pro model has a Bluetooth module with its own separate antenna, both 
located in a plastic bracket to the left side of the hard drive. 




However, unlike the MacBook Pro (17-inch), the Bluetooth bracket in the MacBook Pro (17-inch 
Core 2 Duo) comes wrapped in a foil EMI shield, which can be ordered as a separate part if it is 
rendered unusable for reuse during repair. 

Backup Battery 

The backup battery is not rechargeable. It only provides power to the real time clock and does 
not support system memory. 

Without a power adapter connected, when you swap the finished goods battery in a running 
system, it must be done from sleep. The system will shutdown when you remove the battery. 
When you power back up, it will boot up from SafeSleep, a hibernation state. 

ExpressCard 

ExpressCard has replaced the PCMCIA card cage in the PowerBook G4.The ExpressCard standard 
supports two sizes cards, 34mm and 54mm width. MacBook Pro supports the 34mm standard. 

Unlike the previous PCMCIA design, there is no eject button. The card itself is used to engage and 
disengaged itself from the card cage. In some designs like Ethernet ExpressCard, the card sticks 
out beyond the card cage. It is easy to push on the card to release it. Other cards will be flush 
with the MacBook Pro enclosure and will take a little more care to pop out. 

Speakers 

Both 17-inch MacBook Pro models sport four speakers with two separate speaker modules (left 
and right), each with two speakers each. Each module has expanded housing to produce greater 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Basics— General Information 11 



sound energy than the PowerBook G4. Since the system can output a lot of sound, it is very 
important to make sure screws are properly tightened down. As a mobile product, a loose screw 
can eventually work itself free, and using the speakers at elevated volumes can also work toward 
loosening a screw that is not properly installed. 

In addition, each speaker is driven by its own amplifier, as is the headphone port. As such, 
troubleshooting between speaker and left I/O board failures will require some part swapping to 
pinpoint the problem module (see the Sound heading in Troubleshooting section). 

Infrared Board and the Apple Remote 

The infrared port is placed on the front of the unit just to the left of the display latch button. This 
port is used in conjunction with the Apple Remote provided with each unit. It can be used to 
control Front Row software that manages your music, photos and videos. The remote can also be 
used to control other applications as well. 




iSight Camera 

An iSight Camera is built-in into the display bezel of both 17-inch MacBook Pro models, allowing 
a user to capture video and take still photos. A green LED to the right of the camera glows when 
the camera is on. 

Unlike the standalone iSight camera, the microphone is not integrated with the camera. It is 
located by the left speaker. 

iSight Camera Status LED 



The opening for the green status LED to the right of the camera on the 
MacBook Pro (17-inch) no longer appears in the display bezel. When the 
LED lights up on the MacBook Pro (17-inch Core 2 Duo), it is now visible 
through a clever pattern of micro perforations.

Electrostatic Discharge (ESD) 

Use a properly grounded ESD wrist strap and mat when working on the inside of the computer. 

Service Manual Note 

In this manual, graphics or photos are intended to help illustrate procedures or information only, 
and may show different levels of disassembly, board colors, configurations, or computer models, 
than your computer. 

Kapton® Tape Note 

Kapton tape is used to secure cables and connectors where necessary. 

During disassembly, note any Kapton tape use and locations— reapply in the same manner. Do 
not over apply or build up tape on top of old tape; space tolerances are tight and build up or 
extraneous use of tape may cause pressure on other components. 

Cable Routing Note 

The MacBook Pro matches the same one-inch enclosure height established with the PowerBook 
G4 17-inch series of systems. More so than ever, the placement of parts and wiring is critical. 

During disassembly, note cable routing. Reassemble in the same manner. Verify that cables do 
not route over components when they should route into lower positions or channels. Verify that 
the cables are not strained or applying pressure onto other components. 

Screw Measurement and Callout Note 

All screw measurements given are the specified full length. Actual measured lengths may vary. 
Screw part numbers were assigned using a pre-production unit and are subject to change. 

Temperature Concerns 

The customer may perceive this system to run hotter than previous models. However, the normal 
operating temperature is well within national and international safety standards. Still, customers 
may be concerned about the heat generated by their machine. To prevent an unnecessary repair, 
you can compare a customer's computer to a running model, if available, at your repair site. 

For more information on temperature concerns and customer perception, refer to Knowledge 
Base article 30612: Apple Notebooks: Operating Temperature .

Warning: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. Do not touch the 
glue at any time. Before opening the glue, review the safety instructions below. 

Important: The glue tube included in the kit is sealed until first use. Do not break the seal 
until you are ready to use the glue. To break the seal, hold the tube upright and away from 
you. Place the hollow nozzle cap on the tube and tighten it all the way down. The tube is 
then ready to dispense the glue through the nozzle cap. 




5. Apply one drop of glue to the plug on the bottom case. Do not spread the glue. 

6. Using tweezers or needlenose pliers, carefully position the new foot so its textured surface 
fits into the inner ring of the plug. 

7. Using the end of the tweezers or pliers— not your finger— lightly press and hold the foot in 
place for 30 seconds. 




8. Before turning over the computer, allow the glue to set for at least 15 minutes. 

9. Discard the tube of glue. 

SAFETY INSTRUCTIONS: GLUE IS AN EYE AND SKIN IRRITANT. BONDS SKIN INSTANTLY. 
Contains ethyl cyanoacrylate. Avoid contact with skin and eyes. If eye or mouth contact occurs, 
hold eyelid or mouth open and rinse thoroughly but gently with water only for 15 minutes and 
GET MEDICAL ATTENTION. Liquid glue will sting eye temporarily. Solidified glue may irritate eye 
like a grain of sand and should be treated by an eye doctor. 

If skin bonding occurs, soak in acetone-based nail polish remover or warm soapy water and 
carefully peel or roll skin apart (do not pull). Contact through clothing may cause skin burn. 
If spilled on clothing, flush with cold water. Avoid prolonged breathing of vapors. Use with 
adequate ventilation. KEEP OUT OF REACH OF CHILDREN.

Important Notes: 

All 17-inch MacBook Pro keyboards are not interchangeable with previous PowerBook 
models. Verify that the correct replacement keyboard is ordered, and/or top case if replacing. 
In addition, the MacBook Pro (17-inch Core 2 Duo) keyboard is not interchangeable with the 
MacBook Pro (17-inch). The Caps Lock key was remapped to address a developer escalation. 
The keyboard comes as a multi-layered assembly, and includes backlighting. Do not 
disassemble the keyboard assembly. Dust, fingerprints, or misalignment, can cause improper 
function and damage. 

1. On a clean flat surface, turn the top case upside down. 

2. Locate the small flex connector, shown.

MacBook Pro (17-inch & 17-inch Core 2 Duo) Take Apart — Logic Board 110 



Procedure 

There are two ways to remove the logic board: 

Method 1: Separate the logic board from the heatsink, as usual, then reinstall thermal 
material when reinstalling. 

Method 2: Keep the logic board together with the heatsink and fans, thus avoiding the need 
to replace thermal material. 

If not replacing the logic board or heat sink, but removing the board to facilitate another 
procedure, such as replacing the right speaker or bottom case, then use method 2, if desired. 

Warning: Allowing a logic board to flex, even slightly, can damage solder joints to 
components. To avoid flexing, hold the board vertically along the wide sides. Do not hold 
the board by the ends or by the narrow neck at the fan cutout, or horizontally, as the board's 
weight can cause flex.

3. Warning: If the logic board was removed to facilitate another procedure and will 
be reinstalled, the existing thermal grease cannot be left on the board and must be 
completely cleaned off, since it will create a thermal barrier if combined with new grease. 

Use the following procedures to clean off the old thermal grease— or overheating and 
damage can result. 

4. Use a black stick to remove the grease from the mating surfaces of the three chips. 
Important: Use extreme care not to damage the chips or logic board components. 

5. Use alcohol wipes to completely clean the grease from the surfaces and surrounding area.

Use the following procedures to clean off the old thermal grease, and then to reinstall 
new thermal grease— or overheating and damage can result. 

Use a black stick to remove the thermal grease from the three mating surfaces. 

Use alcohol wipes to completely clean the grease from the surfaces and surrounding area. 




MacBook Pro (17-inch & 17-inch Core 2 Duo) Take Apart — Logic Board 121 



Warning: Whenever the logic board is separated from the heatsink, the thermal grease must 
be replaced. Failure to do so can cause the computer to overheat and be damaged. 
Important: Avoid unnecessary contact with new thermal material, as dirt and body oils 
reduce the material's conductivity. 

Note the contents of the syringe of thermal grease. Important: One syringe (922-7144) 
contains 0.3 to 0.35 cubic centimeters (cc) of thermal grease. That is enough for 0.1 to 0.12 cc 
of grease per chip for up to three chips. Use one-third of the syringe contents per chip. Using 
a felt-tip pen, mark the 1/3 points on the syringe before applying the first dab. .

General Information 



Wire and Flex Cables 

Because of its extremely thin enclosure design and dispersed circuit board, the MacBook Pro 
utilizes a large number of flex cables and variety of wire cable harnesses. Many of these cables 
carry multiple types of signals. 

Here is a list of the cables and the signals that run across them. If you notice a group of functions 
not working, it is likely that the cable is not properly inserted or the connector is damaged.

Hardware Diagnostics 

AppleCare offers two diagnostics for MacBook Pro. Apple Hardware Test (AHT) is shipped 
with every machine and targeted for end-users to troubleshoot their machine. Apple Service 
Diagnostics (ASD) is offered to Service Providers for more in-depth troubleshooting. 

Both applications are available for download from Knowledge Base article 112125: Service 
Diagnostics Matrix. http://docs.info.apple.com/article.html?artnum=n2125 

Apple Hardware Test (AHT) 3A105 for MacBook Pro (17-inch) 

Apple Hardware Test (AHT) 3A115 for MacBook Pro (17-inch Core 2 Duo) 

Notes: 

AHT 3A105 and 3A115 are not backwards compatible with previous Macintosh PowerPC- 
based notebook computers. 

Starting with MacBook Pro, the Apple Hardware Test version numbering changed. All Apple 
Hardware Tests will be number sequentially starting with the prefix "3A."This approach will 
provide each AHT release a unique version number and eliminate confusion between the 
same version across different product lines.

Troubleshooting Aids and Tips 

Power Button pads on logic board 

With the top case removed, the power button is disconnected. Instead of having to reconnect the 
top case to turn on the system, there are two pads on the logic board that can be shorted across 
(with a tool like a flat blade screwdriver) to act as the power button. 

These pads are located near the left side of the LVDS cable connector on the logic board. It is 
marked PWR BTN.The pads are separated with a vertical white line. 




Resetting the System Management Controller (SMC) 

Power management is now handled by a chip called SMC (System Management Controller). 
Previously, it was handled by the Power Management Unit (PMU).To reset the SMC: 

1. If the computer is on, turn it off. 

2. Disconnect the power adapter and remove the main battery. 

3. Hold the power button down for five seconds, then release. 

4. Install the main battery and connect the power adapter. 

5. Press the power button to restart the computer. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — General Information 147 



Display off and sleep LED on 

A new state was added to the sleep LED. When the system is running but the video is not turned 
on (for example, briefly upon boot, or when energy saver turns off the video but does not put 
the system to sleep), the sleep LED will light up uninterrupted. This feedback is to help avoid a 
customer's thinking the system is shutdown. It is possible, however, that this signal may fail if 
the system has crashed. As such, you can also use the next test to see if power is present to an 
apparently "off" system. 

System powered test using Caps lock LED 

There are situations when the system is giving indications that it is shut down (no sleep light, no 
hard drive access, screen is dark, no fan, and so on); however, the logic board may still be running. 
In this case, the logic board is drawing power and generating heat. 

Warning: In this situation, if the computer is placed in an enclosed environment like a 
carrying bag, the computer can overheat. 

Check this situation by pressing the caps lock key. If the LED glows, the System Management 
Controller is running on the logic board. If instead, pressing the caps lock key and perhaps other 
methods of waking up the machine have failed, including closing the lid to put it to sleep and 
reopening it to wake it, hold the power button down for six seconds to force a shut down of the 
computer. Restart the system to check if it boots up normally. 

Note: Previously when the keyboard was connected directly to the System Management 
Controller, this method worked under all conditions; however as a USB device, the OS may 
be hung and the keyboard cannot respond. So if the caps lock light does not come on, the 
computer may be drawing power. If in doubt, hold the power button down for six seconds to 
force a shut down of the computer.

Software Troubleshooting Tips and Tools 

All MacBook Pros require an Intel-compatible Mac OS. 

For the MacBook Pro (17-inch), use Mac OS X 10.4.6 or later only. 

For the MacBook Pro (17-inch Core 2 Duo), use Mac OS X 10.4.8 or later only. 

Login window and account 

Mac OS X requires at least one user account to be established. This is the Administrator's account. 
By default, the Accounts system preference pane has the "Log in automatically [Admin's name]" 
checked. This automatic login setting allows the system to boot into the Finder without having a 
login prompt. However, if this box is not checked, you will need a password to get to the Finder. 
In addition, you will need to create a user account after you reinstall system software. 

Customer forgot password 

If the customer forgot the password for the computer: 

1. Insert the MacBook Pro Mac OS X Install Disc 1 DVD. 

2. Restart the computer while holding down the C key on the keyboard. 

3. When the installer appears, chose Reset Password under the Installer Utilities menu 

4. Follow the on-screen instructions. 

Safe Mode 

Safe Mode is the state Mac OS X is in after a Safe Boot. A Safe Boot is a special way to start Mac 
OS X when troubleshooting. Starting up into Safe Mode does five things to simplify the startup 
and operation of your computer: 

1. It forces a directory check of the startup (boot) volume. It is identical to using Disk Utility's 
Repair Disk or the fsck -fy terminal command. 

2. It loads only required kernel extensions (some of the items in /System/Library/Extensions). 

3. It disables all fonts other than those in /System/Library/Fonts 

4. It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/, 
where (uid) is a user ID number such as 501. 

5. It disables all startup items and any Login Items. 

To start up into Safe Mode (to Safe Boot), do this: 

1. Be sure the computer is shut down. 

2. Press the power button. 

3. Immediately after you hear the startup tone, press and hold the Shift key. 

Note: The Shift key should be held as soon as possible after the startup tone but not before. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — General Information 149 



4. Release the Shift key when you see the gray Apple screen and progress indicator (looks like 
a spinning gear). During the startup, you will see "Safe Boot" on the Mac OS X startup screen. 
To leave Safe Mode, restart the computer normally, without holding any keys during startup.

Application compatibility 

With the transition to Intel microprocessors, previous applications written for the PowerPC 
microprocessor have to be re-compiled to be able to work directly with this new microprocessor 
chip. As with other microprocessor transitions, Apple has formed bridges for users and 
developers to aid in the changes— Universal binary and Rosetta. 

Universal binary 

Universal binary is a Mac OS X application created by a developer who modifies and recompiles 
an application so it runs natively on either a PowerPC-based or Intel-based Mac. This application 
can run on older systems and the new MacBook Pro. 

A Universal binary application can work directly with the Core Duo microprocessor. As discussed 
in the following section, older non-native PowerPC applications can still run on MacBook Pro, but 
requires a Mac OS X technology called Rosetta to translate for the Core Duo processor. 

Universal binary applications are marked with the following logo: 




Mac 



* 



Universal 



Rosetta 

Rosetta is a Mac OS X technology which allows PowerPC applications to run on an Intel-based 
Mac. Rosetta works behind the scenes to translate an existing, native, non-Universal application 
(one that was designed to run natively a PowerPC-based Mac, not a Classic application— see 
note) so it can run on an Intel-based Mac— all you have to do is double-click the application! 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — General Information 150 



Note: The Classic (Mac OS 9) application will not run on MacBook Pro. Recommend to customers 
that they upgrade to Mac OS X versions of required applications.

Hardware Symptoms 



How to Use the Symptom Charts 

The Symptom Charts included in this chapter will help you diagnose specific symptoms related 
to the product. 

In this release, a section is dedicated to the normal startup of the Intel-based MacBook Pro (17- 
inch and 17-inch Core 2 Duo), with a dedicated chart to identify and troubleshoof'no power, no 
video" and "power, no video" symptoms. 

The steps to solve a symptom are listed sequentially. You might not need to perform every 
step before the symptom is resolved. Start with the first step, and then test for the symptom. If 
the symptom persists, replace any modules you removed, go to the next step, and test again. 
Continue down the list until the symptom is resolved. 

Startup 

Startup Sequence 

The Intel-based MacBook Pro starts up very much like the previous professional Macintosh 
notebook computers. If power is available to the system, after pushing the power on button the 
system will start to boot up. 

The screen will stay dark. The sleep LED will glow solid. This will last a few seconds. 

As the system boots, a power-on self test (POST) will be performed. See Error Codes listed 

below for failure results. 

If the system is not muted, you will hear a boot beep. The backlight will turn on and the 

sleep LED will turn off. 

The screen is gray in color. The Apple logo will appear and then the turning gear will appear. 

The desktop pattern will show up, as well as the menu bar start populating. 

No Power, No Video 

The computer will not power on (no fan movement, hard drive spin up and display is not lit). 

1. Remove any connected peripherals and eject any ExpressCard. 

2. Check that the battery has enough charge to start the computer by pressing the button next 
to the LEDs on the battery. At least one LED must light solid (not flashing). 

3. Connect a known-good Apple 85W Portable Power Adapter and power cord or plug to a 
known-good power outlet; make sure the DC plug is properly inserted. The DC plug should 
light up, if not, replace left I/O board. If not go to the troubleshooting, MagSafe connector. 

MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — Hardware Symptom Charts 153 



4. Try powering up without the battery installed If it boots, try a known-good battery. If it does 
not boot, replace the battery connector cable. 

5. Reset the System Management Controller. See new procedures under "Resetting the System 
Management Controller (SMC)" in the General Info: Troubleshooting Aids and Tips section. 

6. Boot up the system and check the sleep indicator. If it turns on solid and turns off, the main 
logic board is getting power and completing the boot cycle. If no video appears, there is an 
issue getting video to the display, or system software is corrupted. Try booting from the Mac 
OS X Install DVD. If the light does not turn off, the boot cycle is not being complete. This may 
be caused by the hard drive not being detected by the system, system software corruption, 
or possibly a hardware issue. 

7. Press Caps Lock key to see if the keycap LED comes on. If it does, hold the power button 
down for six seconds to shut down the computer and restart. 

8. If it still doesn't start, verify that the power button cable is connected properly to the top 
case flex cable assembly and that the flex cable is connected correctly to the logic board. If 
the power button is damaged or not functioning correctly, replace the top case. 

9. Disconnect the keyboard completely. Inspect the connectors. Restart with the keyboard 
disconnected. 

10. Remove any additional RAM. 

11. Try removing the AirPort Extreme card from its socket and start the computer. If it starts, 
shut it down and check the flex cable connector and the connector on the logic board and 
replace the damaged parts. 

1 2. Reseat these flex cables: 

• Left I/O flex cable 

• Hard drive flex cable (will boot to flashing folder if not connected or corrupt) 

• Optical drive flex cable 
•Trackpad flex cable 

• Display LVDS cable 
•Thermal sensor cables 

13. If the computer starts up, inspect the flex cable connector and its terminal on the logic 
board for damage and replace the damaged parts. 

14. Try known-good left I/O board. 

15. Replace logic board. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — Hardware Symptom Charts 154 



Power-On Self Test (POST) Error Codes 

The computer automatically performs a power-on self test when it is turned on after being fully 
shut down (not a restart). This section describes what to do if beeps are heard during the startup. 
When this occurs, the sleep LED will stay on, occasionally flashing. 

MacBook Pro relies on a combination of tones and blinking sleep LEDs to display power-on self 
test (POST) error codes. 

If the computer detects no SDRAM (Synchronous Dynamic Random Access Memory, also referred 
to as RAM), or the RAM installed does not meet the appropriate specifications, the screen will 
remain black but the power LED on the front of the computer will blink once per second to 
signal the error. This error condition may be due to physically damaged RAM, installing the 
incorrect type of RAM, or not having RAM installed. 

Some RAM may appear to pass the power-on self test (POST) but still cannot be used by the 
operating system. In this case, the computer will display a gray screen, sound three tones and 
blink the power LED on the front of the computer three times, pause, and repeat the blinking 
until the computer is turned off.

Short battery life 

Three categories to consider: 

There is a system issue (not the battery). 

If you have the customer's power adapter, plug it into a known good outlet and verify 

that it can charge the system. Also make sure it is the correct 85W adapter. 

Plug a known good 85W adapter into a known good outlet. Verify that the DC connector 

is fully seated into the computer. 

Check whether the customer's system is setup for heavy battery power use (AirPort on, 

optical media always in drive, Energy Savings set to Highest Performance, etc.) 

Test the computer with all third-party devices (printers, hubs, third-party keyboard or 

mouse) removed. 

Reset the System Management Controller. See new procedures under "Resetting 

the System Management Controller (SMC)" in the previous chapter, General Info: 

Troubleshooting Aids and Tips section. 
The battery needs calibration, or it is nearing the end of its useful life. 

Calibration should be done when you first use the battery, and every few months after. It 

allows the battery to properly calculate how much power is left in the battery. 

The battery is a consumable part. It can be charged and discharged only so many cycles 

before it becomes depleted and can no longer hold a charge. 

Note: The battery calibration procedure is as follows: 

1. Plug in the power adapter and fully charge your battery until the light on the power 
adapter plug changes to green and the onscreen meter in the menu bar indicates 
that the battery is fully charged. 

2. Allow the battery to rest in the fully charged state for two hours or longer. You may 
use your computer during this time as long as the adapter is plugged in. 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — Hardware Symptom Charts 160 



3. Disconnect the power adapter with the computer on and start running it from the 
battery. You may use your computer during this time. When your battery gets low, 
you will see the low battery warning dialog on the screen. 

4. Continue to keep your computer turned on until it goes to sleep. 

Note: Save all your work and close all applications when the battery gets low, before 
the system goes to sleep. 

5. Turn off the computer or allow it to sleep for five hours or longer. 

6. Connect the power adapter and leave it connected until the battery is fully 
recharged again. 

The battery has a defect. 

Symptoms include, but are not limited to, a relatively new battery that will not charge 
at all, reports an "X" in the menu bar icon, or status light on its case that will not go out. 
In the first two cases, the battery may need calibration— try this first. In addition, after 
troubleshooting at the system level, if it is demonstrated that the battery is causing 
abrupt shut-downs or goes to sleep without warning, the battery can be considered 
severely degraded and follow the criteria below. 

Warranty Note: If the battery was purchased (either with the computer or as a 
standalone part) in the last 90 days and exhibits severely degraded performance (as 
defined above) provide an in-warranty replacement. If the battery was purchased 
between the last 90 to 365 days, have the customer calibrate their battery. If after 
recalibration, the battery still exhibits severely degraded performance, then provide 
an in-warranty replacement. If the battery was purchased more than 365 days ago, the 
customer will need to purchase a new battery.

Display 

Display latch not working 

Note: When the display is being closed, two latch hooks in the top of the display housing 
should be magnetically pulled down through the slots in the top case and secured by the latch 
mechanism. When the latch button is pushed, the hook should release and retract into the 
display housing. 

If the latch hook is broken, replace the display latch hook assembly. 

When displaying a single color over the screen area, the LCD panel shows one or 
more pixels that are not properly lit 

To determine whether or not the display has an acceptable number of pixel anomalies, follow the 
steps below: 

1. Set the display image to one of the following colors: all-white display, all-red display, all-green 
display, or all-blue display. Knowledge Base article 112125: Service Diagnostics Matrix , has 
the LCD Tester Diagnostic Utility that will generate these patterns on the screen. 

2. Using a jeweler's loupe, pocket microscope, or other magnifying device, identify and count 
each pixel anomaly: 

• Bright subpixel anomaly = subpixel that is always on 

• Dark subpixel anomaly = subpixel that is always off 

3. The number of acceptable pixel anomalies for this system is: 
Acceptable Number of Subpixel Anomalies 



Bright 


Up to 3 


Dark 


Up to 5 


Combination 


Up to 7 



MacBook Pro (17-inch & 17-inch Core 2 Duo) Troubleshooting — Hardware Symptom Charts 162 



If the number of subpixel anomalies exceeds the acceptable number listed in the above 
chart, replace the display panel assembly. 



Replace 



Bright 


4 or more 


Dark 


6 or more 


Combination 


8 or more 



5. If the number of subpixel anomalies is acceptable, explain to the customer that the pixel 
anomalies are within specifications, and no repair is necessary. 

Important: Do not release the specifications to customers. Instead, inform them that a certain 
number of subpixel anomalies are considered acceptable, and these factors apply to all 
manufacturers using LCD technology— not just Apple products. 

When speaking with customers, please use the following explanation: 

Active-matrix LCD technology uses rows and columns of addressable locations (pixels) that 
render text and images on screen. Each pixel location has three separate subpixels (red, green, 
and blue) that allow the image to be rendered in full color. Each subpixel has a corresponding 
transistor responsible for turning the subpixel on or off. 

There are typically millions of these subpixels on an LCD display. For example, the LCD panel used 
in the Apple Cinema HD display is made up of 2.3 million pixels and 6.9 million red, green, and 
blue subpixels. Occasionally, a transistor does not work perfectly, which may result in the affected 
subpixel being turned on (bright) or turned off (dark). With the millions of subpixels on a display, 
it is quite possible to have a low number of faulty transistors on an LCD. Therefore, a certain 
number of subpixel anomalies are considered acceptable. Rejecting all but perfect LCD panels 
would significantly increase the retail price for products using LCD displays. These factors apply 
to all manufacturers using LCD technology— not just Apple products.

Difficulty writing to optical media 

1. Verify the correct type of disc is being used. 

2. Try a different brand or speed of CD-R disc. 

Note: Some brands of 24x or 32x CD-R media may not work with the SuperDrive. 
Note: There are two factors in the ability for the optical drive to write to media. 

- First, there are varying qualities of blank optical media. Some media are made to such low 
specifications that the ability for the drive to write to it is marginal. There are variations in 
optical media even under the same brand. Some brands source their optical media from a 
variety of manufacturers, so there may be variations in the quality. 

- Second, an optical drive that supports writing to a CD-R/RW or DVD-R/RW disc requires 

a special writing algorithm for discs from different disc manufacturers. There are hundreds 
of disc manufacturers, it is impossible to implement writing algorithms for each disc 
manufacturer. Usually, drive manufacturers implement special writing algorithms for discs 
from major disc manufacturers. For discs that are not supported by the drive with special 
writing algorithms, the drive will use a generic writing algorithm to write the disc. In this 
case, the writability and readability may not be optimal. 

3. Replace optical drive flex cable. 

4. Replace optical drive.

Architecture 



The architecture of the MacBook Pro is based on the Intel Core 2 Duo microprocessor and two 
integrated circuits (ICs):the North Bridge memory controller and the South Bridge I/O controller, 
connected to each other by a Direct Media Interface (DMI) bus. The North Bridge IC provides the 
bridging functionality among the processor, the memory system, the DMI bus, and the 16-lane 
PCI Express bus to the graphics controller. The South Bridge IC supports these components: 



Ultra ATA/100 bus for the optical drive (running at UATA/66) 

A 1.5 Gbps Serial ATA (SATA) bus for the hard disk drive 

1-lane PCI Express link for the AirPort Extreme module, 1 for Ethernet, and 1 for ExpressCard 

SPI bus, direct memory access bus to the boot ROM 

USB 2.0 controller, which in turn supports the Bluetooth module, IR receiver, built-in iSight 

camera, built-in trackpad and keyboard, ExpressCard 34 mm slot, and 2 USB 2.0 ports 

Channel to the audio subsystem 

33MHz, 32-bit internal PCI bus to the FireWire 400 (1394a) and FireWire 800 (1394b) 

Direct Media Interface (DMI) bus 



Figure 1 provides a simplified block diagram of the North Bridge and South Bridge ICs and the 
buses that connect them together.
